Specification of Letters Patent.

Patented April 6, 1909.

Application led June 4, 19.06. Serial No. 320,160.

`To all whom 'it may conce-rn:

Be it known that I, COLOMAN DE KANDO, engineer, a subject of theKing ofHun ary, residing at' Budapest, Austria-Hungary, lave invented certainnew and useful Im rovements in Vehicles; and I do hereby eclare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to a vehicle frame and more particularly to meansfor supporting automobile and other vehicle frames on their axles, so asto render same b means of their free ends with Swingin an effectivespring support as lig t and resilient as ossible.

`The velliicle yframe is composed according to my invention of aframework of steeltubes comprisino` two steel-tubes arranged in thelongitudinal` direction of the carriage. 'Vithin the hollow space ofthese longitudinal tubes and secured to the central part thereof arearranged torsion-sprin -bars the free ends of which are rotatab ysupported in bearings provided at the open ends of the tubes. Saidspring-bars are provided on arms or hooks by means of which the who eframe is susended on the carriage axles hy means of exible or otherintermediate members.

My invention relates further to special means for fastening the innerends of the spring-bars to the central part of the longitudinal frametubes and to means for adjusting the swinging arms on said spring-bars.

The invention is described with reference to the annexed drawings, inwhich- Figure 1 is a rear view of a carriage according to my invention;Fig. 2 is a side elevation of a modied form of the lower vehicle frame;Fi'.. 3 is a plan view of the frame shown in Fig. 2 and Fig. 4 is airont elevation of it.

Fi 5 is a sectional elevation of a longitudina frame tube with the 'sring bar therein; Fig. 6 is the spring bar on arger scale; Fig. 7 is thesleeve and the adjacent parts ioriixing the spring rods in thelongitudinal frame tube; Fig. 8 is a cross section on the line 8"-8 ofFig. 7 but with the spring rod fitted in; Fig. 9 shows the adjustingdevice for the swinging arm on the spring bar.

Referring to Fig. 1, 1 is the lower vehicle frame, 2 is the rear axle,3, 3 are links pivoted.,

at 4 and 5, 5 are swmging arms lixed on spring bars as will be describedmore fully hereinafter. The free ends, of the swinging arms 5 are formedwith hooks 6 engaging in the links 3, 3. l

The vehicle frame shown in Figs. 2-4 comrisesl an upper frame 7, 8, 9and a lower rame. This latter comprises two longitudinal tubes 10, 10which are united by means of a plurality of cross-tubes to a rigidframework with the upper frame, as shown in the drawing. Within thelongitudinal tubes 10, 10 are located spring bars as shown in dottedlines in Fig. 2 and in the sectional view Fig. 5.

The inner ends 12 'of the spring bars are fastened in any suitablemanner to the longitudinal tubes 10 at the central part .of the tubesviz. at 13 in Fig. 2.

- A ve simple and efficient manner for fas tening t e spring rods to thetubes and espe- (ially on thin walled tubes, is shown in Figs.

In Fig. 7 the center art of the tube 10 is shown. In vthis tube t ere isiitted a sleeve 14; this sleeve 14 has a c lindrical bore 15 which isconically enlarge on both ends at 16 and 17. The periphery of the sleeveis provided on the outer surface with longitudif' nal grooves 18,wherein the wall of the tube 10 is driven,'in a way to secure the sleeve14 within the tube. To protect this part of the tube and to render itmore rigid a collar 20 is slid on the tube 10 covering the corrugatedpart. The inner surface of the sleeve 14 is provided with teeth 19,formed by a number of longitudinal rooves.

The inner en 12 of the spring bar is provided with similar teethlike apinion and is ada ted to t closely into thetoothed bore of t e sleeve14, whereby when the spring rod is fitted in the sleeve 14, it issecured firmly against any turning caused by the torque l acting on thesprin rod.

The outer free en of the spring rod is rovided with two smooth surfacesor co ars 21, 22 and an intermediate-collar 23 of larger diameter. Thesecollars serve for the 'ournaling of the free end of the spring ro srespectively in boxes rovided at the mouth of tubes 10. The col ar 23serves for securing the swinging arm 5. The collar 23 is for this purose provided with a groove 24 (Fig. 6 an y'9) with a radial face 25. Thebore ofthe hub 26 of the swinging arm 5 has a rectangular recess 27 sothat a key 28 may he placed between the radial face 25 of the groove 24and the recess 27. The hub of the swinging threaded bore. with a screwbolt .2Q-and a jam-nut 30. When the spring bar is fitted with the swining arm 5 in the manner shown 1n Fig. '5 9 anthe brass 31 (Fig. is lacedon the neck 22, the head 12 of the spring rod willbe fitted in theapproximate correct posltlon into the sleeve 14 of the longitudinal tube10, whereby the brass 31 fits in the mouth of the Atube 10.

' The end of the tube 10 is solderedto the joint piece 32, the arm 33 ofwhich is provided with a screw-threaded bore and a cap 34 screwedtherein. The ca 34 ts on the trunnion 21 of the spring ro When thecarriage is suspended by means of the swinging arms. 5 on the axles and1t 1s observed that the swing arms are not m the position required, theyma be adJusted by means of the set screws 29 y the turning-of which theangular position of the swinging arm 5 on the spring rod is altered.
